PBB frame forwarding
Figure 66 PBB frame forwarding
As shown in Figure 66 , a PBB frame is forwarded in the PBBN as follows:
1. BEB 1 encapsulates a customer frame with the corresponding B-MAC, B-VLAN, and I-SID. Then it
forwards the frame to the BCB through its uplink port.
2. BCB forwards the PBB frame from BEB 1 to BEB 2 according to the frame's B-MAC and B-VLAN.
3.
BEB 2 removes the PBB encapsulation, and then forwards the Ethernet frame out of the downlink
port to the customer network.
